T. A. Barron would treats setting on par with characters--equally as alive and complex.
The author T. A. Barron discusses how he had authored a text about a tree that was, what he noted as, a tree’s biography. It should be noted, however, that even though a tree is alive, a tree is typically understood to be inanimate because it is not alive in the same was as an animal. This means that whenever trees are mentioned in writing, they are typically just background/part of the setting. That said, by noting he had written a tree’s biography and considers trees characters, what that implies is that he, too, would treat setting in his work as alive and on equal ground as a regular characters because of the way he considers trees (what are typically just part of the setting) as tantamount with animate objects.
